What is Scratch Testing \/ Scratch Resistance?<\/h2>\n

Scratch testing \/ scratch resistance involves testing the scratch resistance of surfaces in vehicle interiors. The standard assesses how resistant visible surfaces are to scratches caused by fingernails, jewelry, or other objects. <\/p>\n

Test Method<\/h2>\n

Typical Scratch Methods:<\/strong>
\u2022 Erichsen Scratch Test:<\/strong> Defined force (0.5\u201320 N) with steel tip (R = 1 mm)
\u2022 Fingernail Simulation:<\/strong> Rounded tip, 3\u201310 N
\u2022 Crockmeter Test:<\/strong> Linear rubbing body, 9 N<\/p>\n

Evaluation:<\/strong>
\u2022 Visual assessment under standard light D65, scale 1\u20135
\u2022 Gloss change \u0394G at 60\u00b0 (ISO 2813)
\u2022 Color difference \u0394E* (CIE Lab)<\/p>\n

Frequently Asked Questions about Scratch Testing \/ Scratch Resistance<\/h2>\n

How is scratch resistance evaluated?<\/h3>\n

Typically three-stage: Visual assessment under D65 standard light (scale 1\u20135), gloss change \u0394G at 60\u00b0 according to ISO 2813, and color difference \u0394E* in the CIE Lab color space. Grade 1 = no visible scratch. <\/p>\n

Which test forces are used?<\/h3>\n

Depending on the method: 0.5\u201320 N for the Erichsen scratch test, 3\u201310 N for fingernail simulation, 9 N for the Crockmeter. The critical force at which visible scratches appear is documented. <\/p>\n

Which surfaces are particularly susceptible to scratches?<\/h3>\n

High-gloss piano lacquer surfaces and soft-touch coatings. These are most frequently stressed in vehicles (center console, door handles, switches). Grained surfaces are generally more scratch-resistant than smooth ones. <\/p>\n
